Abstract
An electric motor-powered centrifugal compressor having serially connected low- and high-pressure stages includes journal bearings for the shaft of the compressor, the journal bearings being contained in a motor housing that defines a motor cavity enclosing the electric motor. A labyrinth seal is arranged between the high-pressure compressor wheel and the adjacent journal bearing. The labyrinth seal allows a metered flow of fluid, constituting a fraction of the main fluid flow, to pass the labyrinth seal and flow through the journal bearing into the motor cavity for cooling the journal bearing.
